and the said 'furnace is cylindrical in shape, disposed vertically, and provided in its lower portion with a bridge wall B extending diamotrically and dividing they lower portion of the furnace into a burning. compartment- C and an evaporating compartment D, while the upper portion of the furnace forms a combustion chamber E.

The bridge wall B is built of checker brick in two parallel sections spaced apart to 'forni a channel B, connected at its lower end with air inlets B'l arranged in the side wall of the furnace A and controlled at their outer ends by doors B3, as plainly indicated in Fig, ll, so that more or less air can be admitted to the air inlets B2 and to the space Il', delivering air by checker brick openings to both compartments C and D and also to the combustion chamber E.

The burning compartment C is for burning` solid .material and is provided in its bottoni with a sectional grate C below which is the ash pit C2, and in the side wall of the furnace A aliove the grate C are arranged a. series of steam disassociators or jets C, preferably of the construction of the one shown and described in the Letters Patentof the United States for a smoke consuming; tornare, Serial No. 880,380, granted to me February 25, 1908, so that further description of the said disassociators C3 is not deemed necessary. Fuel doors C4 lead to `the `girate C for supplying the saine with fuel for a preliminary heating of the furnace, and doors C lead to the. ash pit C2 tor the removal of the residue of combustion, and which residue forms a product for fertilizing and other purposes.

The evaporating compartment D is used for eraporating liquid and semi-liquids, and the said evaporating compartment l) is provided with an inclined bottom D having horizontal corrugations, into the upper one oi which is discharged liquid or semisliquid matter to be evaporatedyai` that the said liquid or semi-liquid can run down the different corrugations to be gradually evapo- "i'ated by the heat in the Jfurnace. A supply pipe F is arranged outside of the furnace A and terminates at its lower end in a vertical member F discharging into the upper corrugations of the bottom D', and the upperl end F2 of the supply pipe F extends into the combustion chamber E and supports a hopper or catch basin 173, into which is disvcharged the liquid or semilliquid matter to y be evaporated in the compartment D.

tial of a tube G mounted to turn in a bush- -ing extending centrally in the top of the furnace or cupola A, and also -extending through the licor of a platform vI arranged above the cupola and having a gangway I leading to the platform l, so as to permit the matter tobe incinerated to be carried up on the platform by carts or other suitable means. The lower end of the tube G .terminates in an. angular discharge end G adapted to register with the hopper F3, as

plainly indicated in full ylines in Fig. l, or to deliver the solid matter to the compartment C Whenever the tube Gas turned to swing the angular discharge end G into the position shown in dotteddines in Fig. 1. The upper end of the tube Gterminates in a hopper G2 for receiving the matter to be treated from the car"or other nieansen'l ployed, 4and at the junction of the tube G Withthe hopper G2 is arranged -a tiltable sieve G3, which retains 'the solid matter for the time being, While the liquid. and semiliquid vmatter passes through the meshes of the sieve and down the tube G and its end G into the hopper F3, to be delivered tofthe evaporating compartment D. When this has been done a half turn is given to the tube G and then the sieve G3 is turned into an open position so that the solid material can pass down the tube G and to the angular end G', to finally drop into-the burning ccmpartment C. The tube G is provided-With track WheelsGt, traveling on aicircular track l2 held on the bottom of the platform concentric With the bushing H, and on the tube Gis secured a lever J under the control of the operator for turning the tube G to cause the'same to assume the two positions above described, forfeeding liquid and semi-liquid matter into the compartment D and the solid matter into the compartment C. The lever J is adapted to engage with notches in a segment J to lock the separating and feeding device in either of its two' positions above described. Y i

The lower end of the evaporating chamber D is connected by ports or Aopenings li with atboiler chamber L of semi-circular shape and located at the outside of the furnace A adjacent to the compartment D, as will be readily. understood by reference to Fig. 4. In this boiler 'chamberL above the openings K are arranged vertically-disposed steamboilers N, of any approved construction, for generating steam, part of which is used in the steam disassociators Cf* by connecting the boilers N by a pipe N with the said disassociators. The surplus or the remaining portion of the steam not used in the disassociators C3 is carried off by a pipe N2 for driving machinery for the generation of electricity for electric lighting, etc. The boiler chamber L is connected below and above the boilers N by openings P and P with a stack Q, for producing the desired draft in the furnace, and in the said stack Q, is arranged a damper R, and in the opening I is arranged 'a damper R so that by the luse of the dampers R and R the products of combustion'passing intol the boiler chamber L can be controlled'and retained in the said chamber L or allowed to pass into the stack i Q, according to requirement. The boiler chamber L is provided at the 'ends with doors L to permit of gaining access to the said chamber and its boilers N for convenient cleaning,l repairing and other purposes. yThe operation is as follows: In starting the furnace, it is ldesirable that the same be rst heated, and for this urpose a coal lire is started on the grate to heat up the interior of the furnace A 4as Well as the bridge Wall B. When this has been done the matter to be incinerated is discharged into the hopper G2 so that the semi-liquid matter is separated from the solid matter, and the liquid and semi-liquid matter is first discharged into the hopper F, to be fedl onto the bottom D of the evaporating compartment D, in which lat` ter the said liquid and semi-liquid matter is quickly evaporated owing to the heat in the furnace. After the liquid 'and semi-liquid matter is discharged into the compartment D, the operator turns the tube G, as previously explained, and then tilts the sieve Gs into avertical position so that the solid matter contained in the hopper. G2 passes down the tube G to be discharged through the end G into the compartment C in which the solid matter is ignited and burned from the burning fuel on the grate C. Thus additional heat is generated and the smoke arising from the burning fuel inthe compartment C and the vapors arising from the liquid and semi-liquid matter evaporated in the compartment D pass into the combustion liquid and' and gases ile chamber E, to be completely burned. To"

insure complete combustion, air is admitted to fthe combustion chamber E as Well as to the compartments C' and D by operating the doors B3 the desired degree, so that air passesinto the said combustion chamber E and the compartments C and D by Way of the air inlets B2, the air space B and the openings in the checker bricks of the two sec tions of the brick wall B. The products of i ,Goegna et combustion pass through the openings l. into the boiler chamber li for heating the boilers with a, vieu' to `generate steam for the purpose previouel),7 nientionel, it being unile-wreed that the final. passage oit :the products of coi'nl'ius n into the stack Q, are controlled by the po itions of the dainpers E and lt, thus, it desired, the damper l, can be closed to retain the heat in the upper portion o' the ooiler chamber L, While the incoming` products ot combustion can directal.;Y pass from the openings l( through the chamber L and openingr P into the stach Q and up the saine, past the now open damper l When the damper lv is closed and the daniper R 'is open then the products of eonil'iuetion pass up the chamber L to heat the boilers N and to linall): pass by av oil 'the opening l?" into the smoke stack Q. lillhen treating' leeuu-lion id fecal or putrid matter, the latter ou reaching the bottom D ipiicllj,T vaporized, and the vapors rise in the chamber D and pass up into the coinluistion chamber E, 'in which the vapors are gradually hui-ned, and very little oil the Said vapors pass out through the openings K and to the stack Q, so that 'the incinerator is rendered practieallj,7 odorless. lt is understood that when evaporating such fecal or putrid matter sul'liureted, hydrogen gases are lil)- erated, and which, on account ot being lighter 'than the carbon dioxid gases ot com hustion, are forced up into the eon'ibustion elianiher lll and torni a higher strata of gases' 'than the Carbon dioXid. New the flames leaping up into the combustion chamber E continually drjv and rarel;7 the sulifureted gaoes and gradually burn the saine into C02 and SUE, and Finally the residue sinks down in the t'urnaee and passes out through the openirigeA l( into the boiler ehainloer L to liually reach the stack Q. n

lt is understood that by the use of the ineinerator garbage, Waste paper, leaves, carot' dogs, cats, rats and other animals can` lie readily disposed ot, to produit@ ineinerated matter for use as a 'fertilizer and the like, and also to produce steam. for power or heating purposes, thus rendering the ineinerator exceedingly economical for the use o'l municipalities, large manufacturingy concerns and tli'elille,
